A little more digging (ie, masking Python <2.5 and watching the carnage)
revealed that the culprit is the new django-1.0.3.  The diff for the
DEPEND and RDEPEND is:

 RDEPEND="dev-python/imaging
        sqlite? ( || (
+               >=dev-lang/python-2.5[sqlite] )
                ( dev-python/pysqlite:2 <dev-lang/python-2.5 )
-               >=dev-lang/python-2.5[sqlite] ) )
-       test? ( || (
-               ( dev-python/pysqlite:2 <dev-lang/python-2.5 )
-               >=dev-lang/python-2.5[sqlite] ) )
+       )
        postgres? ( dev-python/psycopg )
        mysql? ( >=dev-python/mysql-python-1.2.1_p2 )"
 DEPEND="${RDEPEND}
-       doc? ( >=dev-python/sphinx-0.3 )"
+       doc? ( >=dev-python/sphinx-0.3 )
+       test? ( || (
+               >=dev-lang/python-2.5[sqlite] )
+               ( dev-python/pysqlite:2 <dev-lang/python-2.5 )
+       )"

Does anyone know why these changes would cause <python-2.5 to get pulled
in when I already have python-2.5[sqlite] installed?
